FOREWORD 


Personnel  Specifications  for  enlisted  men  of  the  Tank  Corps 
(complete)  are  herewith  issued. 

It  will  be  noticed  that  Personnel  Specifications  include  the 
Army  title,  the  authorization  of  the  various  grades  according  to 
the  Tables  of  Organization,  the  corresponding  civilian  occupation, 
the  degree  of  skill  at  the  occupation  and  the  occupational  symbol 
(used  in  the  classification  of  all  enlisted  men)  which  are  com- 
monly found  in  the  Tables  of  Occupational  Needs  for  various 
branches  and  corps  of  the  service  heretofore  published.  In  ad- 
dition, Personnel  Specifications  include  a  suggested  substitute 
for  every  civilian  occupation  and  a  description  of  the  duties  of 
each  grade. 

Several  limitations  to  the  complete,  intelligent  use  of  any  sort 
of  tables  of  occupational  organization  of  Army  units  have 
created  the  necessity  for  tables  where  the  duties  of  various 
grades  are  specified.  The  Tables  of  Occupational  Needs  pre- 
scribe the  trade  specialists  required  to  organize  and  maintain 
the  organization  of  well-balanced  units.  The  personnel  office  in 
preparing  a  requisition  for  men  for  the  organization  which  is 
forming  can  from  the  Tables  of  Occupational  Needs  alone  get 
the  material  for  the  telegram  requisitioning  these  men.  But  in 
making  an  assignment  of  the  men  provided  to  fill  the  requisition, 
more  than  the  bare  terms  of  the  civilian  occupation  required 
must  be  taken  into  account  if  the  assignment  is  to  remain  per- 
manent. 

For  two  sergeants,  both  to  be  drawn  from  the  same  occupation, 
one  to  function  as  a  radio  sergeant,  heavy  artillery,  and  the  other 
as  a  sergeant,  first  class,  Air  Service,  the  personnel  officer  would 
make  no  choice  between  two  wireless  operators,  but  would  in- 
discriminately send  one  to  the  regiment  of  heavy  artillery  and 
the  other  to  the  motor  mechanics  regiment.  But  when  he  reads 
in  Personnel  Specifications  for  the  particular  arm  he  is  consider- 
ing the  following  concerning  the  radio  sergeant : 

1  Radio  Sergeant ....  Wireless  or  buzzer  operator  1     Jour.     31w 

Substitute:     Telegrapher. 

Cares  for  and  operates  wireless  apparatus  and 
makes  repairs  under  adverse  conditions.  Re- 
quired to  send  and  receive  fifteen  words  per 
minute. 

while  the  other,  the  sergeant,  first  class,  Air  Service,  is  merely 
defined  as 

1  Wireless  Operator Wireless  operator  1     Jour.     31  w 

Supervises  the  testing  of  repaired  radio  units  and 
accessory  wireless  apparatus. 


he  will  send  the  man  whose  card  shows  more  athletic  activity 
ar-c  greater  mental  alertness  to  the  artillery,  while  the  man  with 
more  academic  ability  in  radio  telegraphy  and  construction  will 
be  sent  to  the  electrical  repair  company  of  the  motor  mechanics 
regiment,  and  both  will  have  much  better  prospects  of  remaining 
in  this  assignment  than  had  a  random  selection  been  made 
merely  from  the  civilian  occupation.  Frequently  the  personnel 
officer  will  find  that  the  definition  of  duties  describes  the  limits 
of  duties.  From  this  may  be  inferred  the  range  of  qualifications 
which  the  man  must  possess  in  order  to  be  of  the  utmost  use  to 
his  company.  In  every  case  he  will  find  the  qualifications  stated 
in  terms  of  what  the  man  actually  does,  for  it  has  been  determined 
that  with  such  a  statement  the  tables  can  be  used  to  greatest  ad- 
vantage both  by  personnel  officers  and  by  commanding  officers. 

The  limitations  upon  successfully  assigning  men  in  a  person- 
nel office  have  created  another  necessity  for  Tables  of  Specifica- 
tion. Not  only  is  some  guide  required  by  the  personnel  officer 
in  making  initial  assignments,  but  it  is  also  necessary  to  point 
the  way  for  the  organization  commander.  It  can  not  be  taken 
for  granted  that  a  man  assigned  by  the  personnel  officer  will  in 
every  instance  function  as  it  is  intended  he  should.  In  some 
instances  it  has  been  found  not  only  that  he  does  not  so  function, 
but  that  he  is  never  given  a  chance  to  do  so.  This  is  not  because 
of  any  opposition  to  giving  him  a  chance  to  demonstrate  how 
far  his  occupational  qualifications  fit  him  for  performing  Army 
duties,  but  because  the  relation  between  the  civilian  occupation 
and  the  Army  duties  is  not  in  every  case  apparent.  In  the  case 
of  cooks  the  relation  is  so  obvious  that  no  one  could  mistake  it, 
but  there  are  other  occupations  the  relations  of  which  to  Army 
duties  are  not  so  patent  as  those  of  cooks.  Right  here  the  tables 
find  their  practical  usefulness.  They  enable  the  company  com- 
mander to  compare  what  the  man  does  in  his  company  with  the 
occupation  which  most  nearly  fits  him  to  perform  these  duties. 
Then  it  is  a  logical  step  to  take  the  Qualification  Cards  and  the 
assignment  as  made  by  the  personnel  officer  and  to  place  the  man 
in  the  position  where  his  occupational  qualifications  relate  to  the 
Army  function. 

Each  set  of  Tables  of  Occupational  Needs  and  Personnel  Speci- 
fications contains  the  following  statement,  which  prescribes  their 
use: 

The  purpose  of  these  tables  is  to  assist  in  fitting  into  the 
Army  civilian  occupational  experience  where  it  will  be  util- 
ized to  the  best  advantage.  Because  of  the  scarcity  of  men 
possessing  trade  ability,  the  occupations  specified  in  these 
tables  have  been  divided  into  two  groups : 

(a)  Those  that  are  essential  to  successful  operation  are 
known  as  the  MAIN  GROUP  and  are  to  be  provided. 

ii 


(b)  Those  that  are  desirable  but  not  entirely  essential  to 
successful  operation  are  listed  under  LESS  ESSENTIAL 
GROUP,  and  are  to  be  fitted  in  as  indicated,  provided  they 
are  available  and  are  not  needed  for  assignment  elsewhere 
in  some  MAIN  GROUP. 

In  the  organization  of  units  requisitions  for  occupation- 
alists  will  therefore,  be  honored  only  in  order  to  complete 
such  MAIN  GROUPS. 

Although  desirable  that  any  or  all  of  the  specialists  called 
for  in  any  LESS  ESSENTIAL  GROUP  should  be  given  a 
particular  assignment,  it  is  best  in  the  first  instance  to  allot 
them  to  each  unit  as  a  whole,  and  it  is  consequently  not  nec- 
essary to  assign  the  men  of  this  group  to  any  particular 
section  of  the  unit ;  and  where,  in  the  following  tables,  the 
totals  of  any  such  LESS  ESSENTIAL  GROUP  have  been 
added  to  any  particular  section  of  a  unit,  it  is  to  be  under- 
stood to  have  been  so  done  for  convenience  in  accounting 
and  not  to  prevent  the  assignment  of  such  specialists  else- 
where in  the  unit,  accordingly  as  their  services  are  needed. 
Moreover,  since  these  specialists  can  not  be  requisitioned, 
their  presence  in  an  organization  depends  upon  whether 
they  are  to  be  found  at  the  station  of  formation  of  the  unit. 
For  these  reasons,  the  LESS  ESSENTIAL  GROUP  is  in 
every  instance  appended  to  the  Tables  of  Personnel  Speci- 
fications. 

The  utilization  of  all  the  resources  of  supply  has  provided  the 
possibility  of  assigning  to  each  organization  the  trade  ability 
actually  required  in  order  to  enable  the  organization  properly  to 
operate.  Moreover,  occupational  specialists  are  quite  as  essen- 
tial to  successful  operation  as  is  equipment  used  by  the  organiza- 
tion in  the  field.  Telegraphers  and  buzzer  operators  are  as 
necessary  to  the  complete  functioning  of  a  Field  Signal  Bat- 
talion as  are  rifles  and  bayonets  to  a  rifle  company  of  the  in- 
fantry regiment.  In  the  first  days  of  the  present  Army  the 
necessity  for  occupational  specialists  was  usually  vague,  and  in- 
coherently expressed  where  it  was  known ;  but  now  the  greater 
expansion  of  the  Army  and  the  increased  specialization  of  units 
have  made  it  necessary  to  secure  to  the  organization  performing 
duties  of  an  intricate  or  technical  nature  men  who  by  periods  of 
civilian  training  at  the  various  arts  and  trades  have  become 
especially  fitted  to  perform  these  functions. 

The  actual  assignment  of  these  specialists  is  qualified  by  con- 
ditions which,  owing  to  the  haste  in  war  training,  it  is  not  pos- 
sible to  overcome.  There  are  certain  occupations  necessary  to 
successful  operation  in  the  field,  which  it  is  not  possible  to  sup- 
ply in  the  number  stated  as  essential  in  the  various  Tables  of 
Personnel  Specifications.  These  occupational  specialists  are  pro- 
duced only  after  many  years  of  civilian  training  and  the  indus- 
tries which  produce  them  are  not  extensively  developed.  The 
number  of  civilians  entering  the  Army  who  possess  trade  ability 

in 


of  a  rare  kind  is  therefore  not  enough  to  fill  the  demand.  To 
meet  this  condition  but  one  solution  is  possible :  To  give  men  of 
civilian  occupations  allied  to  these  rare  ones  a  brief  but  compre- 
hensive period  of  training  in  the  Army  specialty  they  will  be 
called  upon  to  perform.  This  has  in  many  instances  been  done, 
and  when  the  authorization  of  various  Tables  of  Personnel 
Specifications  in  all  staff  corps  and  branches  and  arms  of  the 
service  is  determined,  it  will  be  possible  by  adjusting  the  supply 
to  the  demand  to  foresee  exactly  what  numbers  of  these  men 
must  be  trained  to  fill  the  demand. 

Now  that  these  Tables  are  in  usable  form,  there  no  longer 
remains  any  reason  for  the  misplacement  of  skilled  occupational 
specialists.  Without  good  reason  misplacements  should  in  no 
case  be  permitted.  An  electrical  instrument  maker  or  repair- 
man must  be  used  in  a  Field  Signal  Battalion  on  the  work  for 
.which  he  is  trained,  not  as  assistant  cook.  Specialists  are  un- 
common and  valuable.  It  requires  more  time  to  produce  a  good 
draftsman  than  it  does  to  make  a  bayonet,  yet  the  soldier  is  pro- 
hibited from  chopping  wood  or  opening  cans  with  the  bayonet, 
while  draftsmen  in  many  instances  have  been  used,  not  for  the 
task  for  which  their  training  has  prepared  them,  but  for  duties 
for  which  they  have  had  no  training,  or  which  do  not  challenge 
their  ability.  This  is  wastage  of  the  worst  sort,  for  while  the 
piece  of  materiel  destroyed  can  be  replaced  in  a  short  time  by 
another  which  will  function  quite  as  well,  the  trade  specialist 
lost  to  the  service  can  not.  And  at  the  present  time,  when  every 
person  possessing  trade  ability  has  a  peculiar  place  in  the  Army, 
specialists  assigned  by  personnel  officers  to  organizations  must 
be  thoroughly  tried  out  in  the  place  which  they  are  assigned 
to  fill. 

The  intelligent  use  of  these  tables  is  therefore  as  important 
as  the  occupational  classification  of  the  men  in  making  full  use 
of  the  man -power  of  the  nation.
